A PreCalculus Placement test at CSU Pomona?

<p>I just a message from Pomona saying that I need to take their placement test for pre-calculus?
But what if you already took Pre-Calculus at your community college? I have the pre-cal credit, I have a B+ in Pre-Calculus. Does that mean I still have to take it?
And what happens if I do bad on that test?</p>
